The Small Form Factor Pluggable (SFP) on a simple PCB with some jelly bean components does the job for a point to point link. You need one at each end. If you need to increase the range, you get the appropriate SFP and the right fibre type. The optical test equipment can be leased for the time you need it. -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx]On Behalf Of Steven Kan Sent: Thursday, November 16, 2006 10:01 AM To: SI-List Subject: [SI-LIST] Fiber transceiver assemblies, fully assembled? We have had multiple requests from our customers for a simple ECL-to-fiber transceiver box of some kind, e.g. a finished product with SMA ECL I/Os on one side and a fiber socket on the other, AC wall wart, enclosure, decal, etc. They could lay out a board for a standard commercial transceiver, or buy evaluation boards from the transceiver mfrs, but they typically just want to buy an off-the-shelf, finished product that does the job. The box wouldn't have to have any smarts to it; it would just be a transceiver box. All the encoding, clock recovery, etc. would be done at the electrical level. Do products like this exist? We have a wide variety of just such solutions for translating to/from ECL, PECL, LVDS, TTL, etc., but nothing with optical links. We could try making one with standard parts, but we don't have the optical test equipment necessary to test and support such a device (yet). Applications are typically a few hundred Mbps to a few Gbps, either for isolating two stations from each other or transmitting over long distances. For example I had one such request for LVDS<-->fiber<-->LVDS over a distance of 20 feet because the two stations had a potential between the two of a few kV :) ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl?Si-List_FAQ List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl?Si-List_FAQ List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
